RAID 0+1 Data Recovery

RAID Level 0+1 (0+1) requires a minimum of 4 drives to implement. A RAID 0+1 is a striped array with segments consisting of RAID 0+1 arrays and having the same fault tolerance as RAID level 0+1 plus the overhead fault-tolerance of mirroring. In certain instances a RAID 0+1 array can recover from multiple and simultaneous hard drive failure, however, a single drive failure will cause it to run as RAID 0. Because of limited scalability and high inherent costs, RAID 0+1 is typically used in imaging applications general file servers. It tends to be a high performance solution with reduced emphasis on reliability.

Recovering data from RAID 0+1 Hard Drive Arrays

Because data on a RAID array or volume is typically critical to business continuity, when it becomes inaccessible due to one or more hard drives failing, a bad RAID controller, failed upgrade or damaged striping, it is imperative that you shut the server down and get expert help!

Permanent loss of data often occurs when hard drives are swapped, moved from one position to another or placed in other machines in an attempt to rebuild or repair the array. Formatting a boot drive or partition can also damage or remove striping reducing recoverability of data and causing permanent loss.

The RAID 0+1 data recovery technicians at Advanced Data Recovery, can rebuild failed hard drives, repair damaged RAID 0+1 volumes and recover data your company needs if you call before the damage is too severe. Once platters are damaged, striping overwritten or changed completely,  the chances of getting your data back are slim.

Common RAID 0+1Failures And Data Loss Issues
  • Raid controller failure or configuration changed
  • Two or more hard drives fail or go offline
  • Server crashes and won't remount the array or volume(s)
